_ _ _ Arnold Knopfmacher I'm using Mathematica 3.0 for the Mac, and I'm trying to figure out how to get it to pick a random number that is relatively prime to another number, p-1, where p is prime. In other words, pick a random number k such that 1) k is between 2 and p-1, and 2) k is relatively prime to p-1. How can I do that in Mathematica 3.0? -- Sent via Deja.com http://www.deja.com/ Share what you know. Learn what you don't.
